sign_transparent_input

Convenience function that combines get_sighash and append_signature for cases where the private key is available in memory.

Signature

TypeScript
Go
Kotlin

function sign_transparent_input(
  pczt: WasmPczt,
  input_index: number,
  private_key: string
): WasmPczt

func SignTransparentInput(
  pczt *Pczt,
  inputIndex uint32,
  privateKey []byte,
) (*Pczt, error)

fun signTransparentInput(
  pczt: Pczt,
  inputIndex: UInt,
  privateKey: ByteArray
): Pczt

Parameters

pczt

Pczt

required

The PCZT to sign

input_index

number

required

Index of the transparent input (0-based)

private_key

string

required

32-byte secp256k1 private key (hex)

Returns

Updated PCZT with the signature added.

Example

// Sign input 0
pczt = t2z.sign_transparent_input(pczt, 0, privateKeyHex);

// Sign all inputs
for (let i = 0; i < inputs.length; i++) {
  pczt = t2z.sign_transparent_input(pczt, i, keys[i]);
}

When to Use

Use this function when:

Private key is available in memory
Testing or development
Simple single-party transactions

For hardware wallets or HSMs, use get_sighash + append_signature instead.
